I bought an 11oz Steahly weight for my bike 98 KX250 off ebay and got all but the instructions. Just wanted to make sure I put it on right, I took the bolt off the center of the flywheel and screwed the weight on then I assumed that bar type thing is to help tighten it on? Has 2 bolts to connect it to the weight then use a 1/2" driver to tighten? Right so far I hope ;) Then tighten the little allen head bolts all around, Do you use the stock gasket along with the plastic spacer? I left mine off just because it was torn up anyway, have to get a new one. Just rode it around the yard and seemed to help a little but can't really tell considering my backyard is only 100 ft. long, find out tomm. for sure how it works hopefully.
